With the improving ecological environment of Panjin City, Liaoning Province, an increasing number of rare birds have “settled down” in Liaohe Estuarine Wetland. There are Paradoxornis heudei, a very precious species, Paradoxornis webbianus, Pycnonotus sinensis, and so on. They build their nests here and fly through the forests to their babies with food in their mouths, forming a heart-warming scene.
